Fit - oxford og denim shirts

I just bought three pairs of Ralph Lauren slim fit oxford shirts and a slim fit denim shirt.
I would like your opinion on the fit of the shirt:http://sdrv.ms/11wb5Mahttp://sdrv.ms/11wbePM
The pictures aren't the best, I hope you get the idea of the fit anyway. It's quite difficult to photograph yourself, without the angles getting really weird.
The denim shirt fits almost exactly like the oxford shirts, but tomorrow I'll try to take a few pics of me wearing the oxford shirts.

I curious to hear your opinions, I often gets very unsure when I come home and try my purchases on again, so I really need a second opinion.

It is slightly difficult to determine the exact fit - especially when the sleeves are rolled up - however from what I can see it looks pretty good. No excess fabric and it is pretty slim as you wanted. Nice shirt btw.

Like Alex said, it's a bit hard to make out the exact fit, but it looks pretty good. On that second pic, there looks to be a lot of loose fabric on the back. Could be because of the way your arm is pulled back on it.

It's of course a matter of taste, but when I buy slim fit, I want it to be snug over the back as well as the front. However, a bit of air over the back is nice to have during the summer months.

Yeah, it is actually the back I'm a bit unsure about. But the collar, sleeves and shoulders fit just fine, so I guess they're meant to be a bit loose fitting in the back... The angle the photo is taken from probably make it look worse. I'll try to take a better photo.
I agree with you, Marc I normally prefer slim fit to be slim all over, but it's really hard to find, being a slim tall guy.

I don't own any Ralph Lauren, so I wouldn't know, but I'm guessing they're of a higher quality than your average high street shirt. If so, that means the shirt will last longer, and it may be worthwhile to take it to a tailor, to have the back taken in a bit. It's usually not a very expensive alteration.
